Maybe you all have thought of this, but I was cleaning off the front grills and screens every hour while bush hogging and flail mowing in the tall stuff. All the tractors I have seem to have very difficult screens to clean with and without the tractor running. So I bought a couple of those 18" magnetic tool hanging strips and some window screen material. I rolled it across front and stuck the strips vertically on either side of the hood. It seems to catch less and it is much easier to clean off with a whisk broom. Worked well on the Fergie, the 504 and the SC!
